g alone, it
would take Kevin 21 minutes longer to clear the driveway of snow than it would take Jay working alone. When is the number of minutes it
would take Jay to clear the driveway of snow when working alone, the situation is modeled by this rational equation:
1/j + 1/j +21 = 1/14
How long would it take Jay to clear the driveway of snow working alone?
А.
7 minutes
В.

Find all solutions of cos x -sqrt = 0.
valina [46]

Answer:

Option A

Step-by-step explanation:

Good question!

We assume that x lies on the interval 0<=x<=360. We can therefore identify the solution in degrees:

\cos \left(x\right)-\sqrt{1-3\cos ^2\left(x\right)}=0,\:0\le \:x\le \:360^{\circ \:}

Now we can solve by substitution, and when simplified we get cos(x) = 1/2.

Take the inverse: x = cos^-1(1/2) = π/3 <--- angle in first quadrant

                             x = (2π-π/3) = 5π/3 <----- angle in fourth quadrant

As you know π/3 in degrees is 60, and 5π/3 = 360-60 = 300

Therefore your solution is the first option, x = 60+n360 and x = 300 + n360
